Seeing odd texture artifacts while rendering on a EC2 machine with GPUs
While I solved the problem by removing the displacement map from the PBR material, I'm not 100% certain why the issue wasn't affecting the rendering output when done using a CPU alone.
My understanding so far for why this worked:
Each wall is represented using a few triangles whereas the displacement map needs a finely divided mesh to cause micro displacements to make the surface looks like the material. With only a few large triangles to adjust, the algorithm is unable to do it correctly and the error manifests itself in the form fo this jagged surface.
Please feel free to comment if you know what might be happening here.
